Efficient Online Proportional Sampling with Applications to Smoothed Online Learning

Amirmahdi Mirfakhar, Maria-Florina Balcan, Hedyeh Beyhaghi

The paper proposes a data structure for efficiently performing online proportional sampling over high‑dimensional, piecewise‑structured domains under a σ‑smoothed adversary, and us…

CGES: Confidence-Guided Early Stopping for Efficient and Accurate Self-Consistency

Ehsan Aghazadeh, Ahmad Ghasemi, Hedyeh Beyhaghi +1

Large language models (LLMs) are often queried multiple times at test time, with predictions aggregated by majority vote. While effective, this self-consistency (Wang et al., 2023)…

Two-Sided Time-Independent Regret for Matching Markets with Limited Interviews

Amirmahdi Mirfakhar, Xuchuang Wang, Mengfan Xu +2

Two-sided matching platforms rely on preferences from both sides, yet participants can evaluate only a small fraction of potential partners. In practice, they use low-cost pre-matc…

The Secretary Problem with Predictions and a Chosen Order

Helia Karisani, Mohammadreza Daneshvaramoli, Hedyeh Beyhaghi +2

We study a learning-augmented variant of the secretary problem, recently introduced by Fujii and Yoshida (2023), in which the decision-maker has access to machine-learned predictio…

Competitive Algorithms for Multi-Agent Ski-Rental Problems

Xuchuang Wang, Bo Sun, Hedyeh Beyhaghi +3

This paper introduces a novel multi-agent ski-rental problem that generalizes the classical ski-rental dilemma to a group setting where agents incur individual and shared costs. In…
